The given statement is true
Step-by-step explanation:
Every task has its own completion time. The completion time depends purely on the individual. Each individual completes the task in their own time based on the skill set that they possess to perform the task. Normally the individual overestimate the time by comparing with their immediate supervisor. One should understand that, it is always better to provide the estimated time by oneself so that it is the only practically possible way to meet the deadline. Normally in software development environment, a time frame will be fixed and you must work in additional/ less hours than the estimated hours based on skill set and challenge that you face in completing the task.
